声卡安装请教

（今天终于有时间按照大侠们的指点解决了问题。重新按照文档配置内核，编译系统，alsaconf就能识别声卡，但是不能发声。重新emerge一遍alsa-utils就一切OK了）

声卡安装后，alsaconf不能识别声卡。菜鸟可能只是在安装时出现一些没有意识到的错误，
请高手指正。

编译的内核的时候严格按Gentoo Linux ALSA Guide设置选项：
我和声卡和你的一样，最开始我的内核选项也有错误，不过好在有声音，只是在音量控制里设备显示为：unknow oss mixer(大概是这样子)，后来因为不能看网络电视所以才下决心搞定它，最后发现按Gentoo Linux ALSA Guide设置内核，一点都不费神。
good luck!

提醒兄弟一下，以后贴系统信息的时候用引用的，这样可以区分开来，好看一些，你这样一路贴下来，后面的人看的很费劲。：）

先看看这个吧
尚未审校完毕，不过应该不会有太大问题

感谢wangflove和斑竹:-)的建议，菜鸟机器发声了。
